MI - MI - Richard, 42, & Shirley Robison, 40, & 4 children, Good Hart, 25 June 1968
The person used FOIA to gain access to the investigation files for the murders. There's a reference to a ballistics test done by the Michigan state police that showed a match. The name is redacted, but its fairly obvious it refers to her brother. JMO.
I do think Scolaro did it, but he may have had help. How do you explain things like:
- A stolen car found abandoned years later with a luggage tag in the glove box with Mrs. Robison's name and address on it?
- Possible matching ballistics on a weapon owned by the victim's brother
There are a few other things at the link that are suspicious, though I don't agree with Ted Kackzyinski or the Zodiac theories.
@itsrak I also can't agree yet with the John Norman Collins theory. The news stories report there was cash left at the crime scene, so it doesn't appear there was a robbery. LE thought the cutting of Mrs. Robison's undergarments was an attempt to stage the crime scene to look like a sexually motivated attack. The MO is also completely different from Collins.
As for allegations that Mr. Robison assaulted women, there are none. Can you provide a link?
